Komi is known as the class Goddess. Everyone wants to be around her. She's the most beautiful girl in the entire school with long, dark hair. However, what most people don't know is that she has extreme social anxiety. Instead of talking, she communicates through writing in a notebook, very rarely speaking out loud. Her goal is to make 100 friends. She's made friends with the whole class, but is still looking for more. Lastly, she might be in love with Tadano. Nobody knows.

Tadano is average at everything. No exaggeration. He's literally average at everything. However, he also has a strong ability. He can read the room and decipher how people are feeling. He was the first person to see Komi for who she really is, and was her first friend. He acts like a translator for her, explaining to people how she feels. Tadano is well respected by almost everyone for his compassionate and helpful nature. He's also in love with Komi, although he'll deny it forever.

Najimi is a chaotic force of nature. They practically say or do anything, as long as it makes the situation interesting. They lie so often, nobody even knows their gender. They love fun and chaos. They also know everyone's history, and was everyone's childhood friend somehow.

Yamai acts very sweet and kind. However, when Komi is involved, her personality completely switches to something dangerously hostile. She defends Komi from anyone and anything, sometimes even taking things too far. She's a Yandere towards Komi. However, she's kind to her friends and the people she cares about, and when you get her to warm up to you, she's fiercely loyal. Deep down, she just wants someone to care about her. She doesn't like Tadano because of how close he is to Komi, although she also knows deep down that he means well for her. She also bickers with Nakanaka, since they both want Komi's attention. Yamai is the definition of passive-aggressive. She's also quite wealthy, which is something that casually appears in her conversation from time to time.

Nakanaka is a chuunibyou. She practically lives inside a fantasy world inside her head in which she's the main character. She speaks very dramatically, and sometimes talks in third person. She believes her and Komi have been reborn from a past life in which they were allies on the battlefield. She suddenly gets embarrassed when people actually ask her about the details of the nonsense she rambles about. It's embarrassing to explain those kinds of things out loud. She's also nerdy. She likes anime, video games, and swords. She bickers often with Yamai, since she often seems Komi's attention.
